Check out this fully converted 2018 Mercedes Sprinter. A big congratulations to my sister Cassie on the purchase of this epic van which commences the start of a new adventure to travel the continent! The NEW-WEST GRIZZLY is a Class B RV assembled on the 19½-foot Mercedes Sprinter 2500 4X4 chassis. This vehicle was designed for pleasure by the manufacturer. Therefore, the mechanical unit (engine, transmission , and axle ratio [differential]), are very cost-effective.
